Ball-Bearing Hardplate
One hundred ball bearings encased in hardened
steel and positioned inside the door, between the lock and doorplate.
Protects against attempted drilling, breaking drill bits. This
security feature is offered on all Premium models, including the
Liberty Presidential and Washington, and the National Security
Magnum and Classic.
Bolt Retention System

A rotating cam and shaft system that opens
or closes door locking bolts. This mechanism is offered on all
Deluxe and Value models in the Liberty Safe product family.
Clutch-Drive (Handle Slip) Mechanism
A mechanism designed to resist break-in by allowing
the door handle to slip when excessive force is applied to the
handle. All Liberty and National Security products include this
feature.

Sensory device coupled with layers of
hardened steel positioned between the lock and doorplate. Secures
the door in the locked position if the lock is punched, drilled
or torched in an attempted entry. All Liberty brand models include
this feature.
Gear-Drive Bolt Locking Mechanism
A machined gear system that smoothly opens
or closes door locking bolts. A higher-end mechanism offered on
all Premium models in the Liberty Safe family of products.
Hardened Steel
Steel that has been heat-treated to make
it harder and more difficult to break, bend or penetrate. All
Liberty and National Security safes included various levels of
hardened steel in the doors. Hardened steel in Liberty brand products
is sometimes called Diamalloy™ steel.
HiSecurity™ Composite Door
A unique door design consisting of fireboard
insulation sandwiched between layers of steel and hardened steel
plate. Developed and introduced by Liberty Safe in 1997, this
door design is offered on the Presidential, Washington, Lincoln
and Colonial® models in the Liberty brand.

in an "over-lock" position, making drilling or punching
the bolts nearly impossible. Sometimes called a "Dead Lock"
system. This proprietary design is standard on all National Security
models.

A door constructed of solid sheet steel
with various thickness. Franklin and Residential models in the
Liberty brand, and all National Security safes are constructed
with this door design.

welded to the door edge. This feature makes the door edge stronger,
providing greater protection against prying. The National Security
Magnum model comes standard with a 1" thick reinforced door
edge.
Relocking Devices
Sensory devices located inside the safe
door and lock that secure the door in the locked position in an
attempted attack. National Security models include three relockers,
protecting against punch, drill and torch attacks. All Liberty

against punch or drill attacks (see Fail-Safe™ Relocker).
